How Often Do You File?

post #1 of 21
Thread Starter 
Usually I rarely file my side edges unless they are really dinged or dull.

I was also wondering how many basic touchups on the skis with a diamond stone would be beneficial until the sidewall started to limit the stones contact with the edge material?

Would the sidewall even be an issue over the coarse of one season if it was set once at the begining?

I always thought that back filing or using a sidewall remover once per season was fine but now I am rethinking that.

To answer the topic question.... whenever its needed. What is done depends on what is wrong with the skis. I will always check the edges by lightly running my finger along all four edges the whole length to feel for anything inconsistent with smoothness. If the snow was unaggressive and no ding or damage was found, a quick pass with a medium and fine diamond might be enough. If the snow was firm, then a fine file in a guide for a pass or two before the varying coarsenesses (coarse to medium to fine) of diamonds. For special skis, the final polish gets the extra-fine diamond.

I almost never file my edges but I use a diamond stone lightly every day. When I get new skis, I use a panser file to remove excess sidewall material. I have a device that allows me to remove the material to a 7 degree angle. I do not remove any of the metal at this angle but get the plastic out of the way. Then I can keep the edges at 2.5 or 3 degree with fussy with the sideway anymore.

So once a season should be enough for sidewall removal if done properly?

If not alot of sidewall was removed early on is it possible to start dulling the edge because the stone is only making contact on the sidewall and very edge?

I diamond stone base and side edges nearly every day, except in really soft conditions which don't seem to burr the edges at all. It doesn't seem to me that the stones really remove enough material to effect the base bevel, nor to require sidewall planing.

This year I've found that I've needed to file the side edges about every 6-7 days. My base edges have gotten a bit dinged up, and I've actually lightly filed a couple of specific spots. I know I shouldn't mess with my base edges to avoid excessive base bevel, but I hate to leave dings on them too.

Since I have almost 30 days on them now, I probably should get a stone grind before going away, but doubt that I'll be able to.

You need to remove whatever sidewall plastic will interfere with edge sharpening. On skis with prominent sidewall plastic, there are devices for trimming it back. I've used a sharp chisel to do the same.

I side file with a Sun Valley Tools 2 degree guide whenever I find the skis dulled. If edges are sharp, but I find a burr, I'll just stone the burr. I'm not into "polished" edge surfaces, but I don't race. I bevel the metal base edge 1 degree with a SVT guide, but not the Ptex. If I don't have to do a lot of sideslips and wedging in lessons, my skis remain sharp multiple days. I ski mostly on man-made hardpack, which wears and dulls skis significantly more than softer surfaces.

Me too. You save a LOT of edge by keeping them sharp, smooth and polished daily. Even a minor filing job seems to take off 20-30 times as much edge as a daily touch-up.

Sidewalls only need trimming back when they interfere with the side edge job you are doing - a good indicator is white "topsheet" material on the stone or file.

I almost never file but I just wanted to see what others do.

I assume at some point during the season running a fine tooth file is fine.

After a few bad edge hits at K I had to file because the diamond stones weren't making contact with the very edge because of the long dings and burrs.

That is probably the most damage I have ever done to my edges.

Guess that's why I don't like K too much.

I started using a diamond stone this year and wish I'd started using one long ago. I really did not think they would be very effective---man was I wrong! They leave such a nice sharp smooth edge I am amazed each time I use the darn thing.

One very nice thing about my Tyrolia rail flex bindings is they come off really easy and with virtually no effort I can use the diamond stone in an edge guide and be done in very little time at all.

I used a file once this year on both mine and Bonni's skis and just a diamond since.

I file quite often AND polish with a stone. Skis don't usually last me more than 3 years before they become tele's anyway ...

I have been using diamond stones all along and swear by them but I think that you need to run a file every once in awhile.

Sharpness, as gets mentioned pretty much continuously in these parts, is completely relative - were I to race on skis that had just been maintained by stones, I would be even slower than I am already. If you want skis that are really sharp, you have to file them... If I'm skiing on ice training or racing, my skis get lightly filed more or less every day on snow. That being said, 2 passes with a file will keep the skis sharp if you do it every day, but if you wait longer, the filings really start to pile up if you want a very sharp edge again. there are many standards for sharpness, of course, and if your skis are sharp enough with just a stone, then that's perfect for you!

I file before races which comes out to about once a week. The sidewall issue depends on how much you take off. You just do it on a need be basis. If you pull the sidewall with a bladed sidewall planar, you should be able to go a full season. A high angle file guide and panzar file won't take off as much material close to the edge. Thus, if you file alot, you might have to do it again mid season.

Scalce,
Come on by. I'll give you a clinic. There's nothing wrong with side filing, as long as it is done properly.
Anyone who has the dexterity and the know-how should file their side edges when necessary, and do some diamond stoning in between.
Give me a shout.

for diamond stone, is it better to use it with the guide or without?

Should the base or side edge be done first?

After the diamond stone, should the edge grinding rubber be use on the edge?

With the guide and the stone, if the sidewall is in the way than i guess the angel will change?

A lot of useful information, very detailed

I never file between shop tunes. I use a coarse stone followed by diamond stone after each day of skiing. A diamond stone doesn't work that well if you have really deep burrs. Using as stone like a Arkansas stone will quickly knock down the big burrs and save some wear & tear on your diamond stone. I then followup with a diamond stone to finish up and don't bother with polishing.

I guess the main reason why i don't like to file between major tunes is because I don't want to take off too much material on edges. Also it's hard to get as consistent and smooth a finish like what they can do on machine edger, so I leave the major edge work to the shop.

Hi scalace, hope you and your wife are enjoying winter's resurgence in the northeast. After having two kids go throught the okemo race program I have a pretty good feel for this tuning business. Diamond stone with a 100 or 200 grit stone, follow up with a 400, then 600 or 800 grit depending on your endurance. We use a 50/50 moxture of isopropyl alcohol and water as a lubricant, simulates the "juice" sold in some of the racing catalogues. I use a .5 degree on the base, 2 degrees on the side. Seems to allow some quickness in turning and good edge hold on our hardpack conditions. Be sure to tune from tip to tail with the shaped skis, unless you like having your tails skid out underneath you. good luck.

Ditto.

See you Saturday hairybones. Salomon's Oasis Project will be at the bottom of Chief.

Sorry for the highjack. Scalce, Bonni's out in CO until the 9th.
